IMPROVEMENT IN SIMPLEMENT FOR CUTTING- THRED.

The Schedule referred to in these Letters Patent and making part of thesama.

We, FRIEDRICH EGGF. and ROBERT W. CHURCHILL, of Bridgeport, county ofFairtield, State of Connecticut, have invented certain Improvements inSelvage and Thread-cutting Machines, of which the following is aspecification.

.Naturali-nd Object of our I Jwentt'on.

Onr invention relates to that class of machines or implements, combiningtwo levers, provided with cut- 4ting-edges or knives, to operate on bothsides 'of the material to bc cnt, said levers being constructed incircular form and size suitable to easily slip on the finger.

The object of our invention is to produce a cutting,r implement compactin form, and easily operated by the tinger. i

Description of Accompanying Drawing. Figure l shows the implementadjusted and-ready for use.

Figure 2, a front view of same. Figures 3, 4, 5, and 6, details ot'same.

General Description..

tance from the finger to admit of hinge-joint c, cutter 2, and spring4,'and is connected and operated in conjunction withlever a and cutter lby the pin 3;

We can` construct our invention ot' any ot' the mal- `loable metals. Itsoperation is easily understood.

when the cutters are open, their outer edges reach the joints ot' thefinger when extended.

The material to be cut is placed betweenl the cutters, thc `finger benttoward the palm ofthe hand. .This forces the levers together,.and shutsthe cutters 1 and 2, They, operating with each other, cut'th material. Al

'Ihe cutters 1 and 2, of steel, can bereadily sharpcned by removing pin,and nsinga line file on edges of cut-ter. v

By the addition of ornaments, the implement can be made a neat piece ofjewelry..

XVe do not claim as novel the cutters or hinge-joint of same worked bylevers, only the manner ot' construction and application.

Wc'do not confineonrselves tot-he bending oi the levers to reach thejoints of' the finger.

We can secure flat thinA pieces ot' metal to the nnder periphery of ringor level', 'and let the ring, when at rest, close over and give the form4ot a plain hoopring.

What we claim as our invention, and desire to secure by Letters Patent,is

1. The levers a and d, hinge-joints c and e, cutters 1 and 2, spring 4,constructed as described ,and shown.

2. Av ring-shaped lever cuttingl implement, operated by the finger, asspecified and shown. In testimony whereof we have signed our names tothis specification before two subscribing witnesses.
